The chemical formula would dictate how many ions are present in a solution. It tells how many of what ion would dissociate in the solution. In every chemical reaction or dissociation reaction, it is important to remember that the number of each atoms on each side would be equal.

Determine the number of molecules present in 4.56 moles of nitrogen (n2).
Iteru [2.4K]
To calculate the number of molecules, we can simply use this rule:
number of molecules = number of moles x Avogadro's number

In this problem, we have:
number of moles = 4.56 moles
Avogadro's number is a constant = 6.02 x 10^23

Substituting in the above equation, we can calculate the number of molecules as follows:
number of molecules = 4.56 x 6.02 x 10^23
                                  = 2.74512 x 10^24 molecules

The rate of disappearance of hbr in the gas phase reaction 2hbr(g)?h2(g)+br2(g) is 0.160 m s-1 at 150°c. the rate of appearance
luda_lava [24]
The reaction rates of the substances whether disappearance of a reactant or the appearance of a product are related to each other by the chemical reaction. The reaction rates are related as follows:

rate = rHBr / 2 = rBr2 = rH2

rH2 = 0.160 / 2 = 0.08 M/s
